Question

Write the solution for the following problem as an ordered pair: The sides of a triangle have measures of x, x, and y, and the perimeter of the triangle is 46. The measure y is 4 centimeters longer than the measure x. Be sure to show all work.

Answer 1

x + x +y = 46
y = x + 4

x + x + y = 46
x + x +(x + 4) = 46
x +x + x + 4 = 46
3x + 4 = 46
3x = 46 - 4
3x = 42
x = 42/3
x = 14
y = x + 4
y = 14 + 4
y = 20
so since x = 14 and y = 20 it's (14,20) that's the answer
